Length of the Cycle: Why Does It Matter?
If you're trying to conceive, understanding the length of your menstrual cycle is essential. It can help you identify your most fertile days and plan for pregnancy. Even though some women have perfectly predictable cycles, this is not the case with everyone.
So, what exactly is cycle length, and how is it calculated? Let's break it down step by step.
How Is the Length of the Cycle Calculated?
Many women struggle with calculating their cycle length. Let's make it simple for you.
To calculate your cycle length:
Mark the first day of your period.
Count the days until the day before your next period begins.
This number is the length of your cycle.
For example, if your period starts on the 1st and your next period starts on the 28th, your cycle length is 27 days.
What is Considered a "Norm"?
Many women assume that 28 days is the normal cycle length, and they get stressed when their cycle fluctuates a little.
Well, the reality is there's no "Normal 28 Days" cycle concept in the real world. Cycles anywhere between 21 and 35 days are considered normal.
The slight variation of period length from month to month is perfectly fine. And if your periods stay consistent within about seven days, you're in the "regular" zone.
If your cycle length is shorter than 21 days, it is called polymenorrhea. It can be because of hormone imbalances and unhealthy lifestyles.
On the other hand, a cycle longer than 35 days is called oligomenorrhea. This can be caused by PCOS, PCOD, thyroid dysfunction, stress and age-related changes.
What Can Affect Your Cycle Length?
So many factors can influence your cycle length. Let's see the most common ones:
Follicular phase
Yes, all women have the same physiology, but they do have variations in their genetics. That's why the follicular phase is not the same length for everyone. It is the time your body takes to prepare an egg for ovulation. A longer follicular phase means a longer cycle.
Lifestyle and health
Stress, weight fluctuations, and even excessive exercise can all throw your cycle off.
Medical factors
Conditions like PCOS, thyroid issues, and using certain medications (birth control and fertility treatments) can affect the cycle length.
When Should You See a Doctor?
Remember, not all irregularities cause alarms. But if your cycles are shorter than 21 days, longer than 35 days, or your periods last for more than seven days month-to-month, it's worth checking in with a healthcare provider.
Other Red Flags:
Missing periods altogether
Unusually heavy or painful periods
Sudden changes in your cycle length
Other Important Information
Keeping a track of your cycle is an important part of your reproductive health. It can help you keep a check on your health and detect any abnormal patterns early on.
If you're trying to conceive, tracking your periods can help you time your intercourse and help you get pregnant.
If you have more concerns about your cycle, it is always wiser to talk with your OBGYN.
